P8-29 A closed feedwater heater is used in a Rankine cycle Steam leaves the boiler at 20 MPa, 600°C. Between the high and low-pressure turbines, steam at 1 MPa is extracted and delivered to the closed feedwater heater. Feedwater exits the feedwater heater at 20 MPa and the saturation temperature of the 1-MPa steam; saturated liquid condensate is fed through a steam trap back to the condenser. Steam from the second- stage turbine enters the condenser at 10 kPa, and...

A Steam Rankine Cycle receives fluid from a boiler at 3.5 MN/m2 and 350oC, exhausts to the condenser at 10 kN/m2 and returns the condensate to the boiler via a feed pump. Draw both the system showing plant layout and the cycle on a temperature/entropy graph. Neglecting feed pump work calculate :- The energy supplied per kg of steam. The dryness fraction of the steam entering the condenser. The Rankine efficiency. The Ideal power output if the mass flow rate...
